N. Burbidgeae is found at elevations of between 1200 and 1800 meters.
N. Robcantleyi  is found at elevations of between 1750 and 1850 meters.
On average, a N. Burbidgeae x Robcantleyi hybrid is likely to prefer conditions similar to those found at elevations of between 1475 and 1825 meters. This range is highlighted in purple on the chart above, and equates to temperatures of approximately 24 - 26°C (75 - 78°F) during the day, and 14 - 16°C (57 - 60°F) at night.
This is only an estimate - there are many other factors to consider, particularly for hybrids. These include male & female parentage (remember that Nepenthes are dioecious!) and whether either of the parent species is particularly challenging to grow
